Some elevator buckets 1, 11, 21, 31, 41 have aperture orifices 2, 3, 4, 12, 22; 42, 43, 44, 52. Traditionally, these aperture orifices are formed by drilling a solid bucket wall but by provided aperture features 12', 13', 52' in a moulded bucket with some already moulded aperture orifices then some markers or pre-cursors for aperture orifices are provided and provision of elevator buckets is more efficient with aperture orifices.
